Periods usually begin at around the age of 12, although some girls will start them earlier or later. A delay in starting periods isn't usually a cause for concern. Most girls will be having regular periods by age 16 to 18. I've tested them on long haul flights, overnight, in the office and on my work from home days, and honestly?

PRO: You can wear the best period pants all day without worrying about changing a tampon. You can also wear them to give you extra protection alongside a pad or menstrual cup on heavy flow days, or to protect against incontinence or for peace-of-mind postpartum. When it comes to fabric, period underwear isn’t as straightforward as regular underwear.
